Is this a sleep regression or no?

Hey mamas so my baby has a runny/ blocked nose no temp or any type of cough. Last night she woke up for her a feed around 3am but would not go back to sleep till 5am/5:30am ish she would cry and moan and then later went to sleep. What is this? She is turning 7months tomorrow so unsure if it’s a regression. The nights have been a killer recently
